The STG3856 is a high-speed CMOS low voltage dual analog SP3T (single pole triple throw) switch or dual 3 : 1 multiplexer /demultiplexer switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device ideal for portable applications.


The device offers very low ON resistance (< 1.0 Ω) at VCC = 4.3 V. The disabling and enabling of switches are done by setting the 1IN and 2IN control pins. Additional key features are fast switching speed, and ultra low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.

Key features
  • ESD performance (analog channel vs. GND): HBM > 2 kV (MIL STD 883 method 3015)
  • Latch-up performance exceeds 300 mA (JESD 17)
  • High speed: tPD = 0.3 ns (typ.) at VCC = 3.0 V tPD = 0.4 ns (typ.) at VCC = 2.3 V
  • Low ON resistance VIN = 0 V: RON = 1.0 Ω(max. TA = 25°C) at VCC = 4.3 V RON = 1.5 Ω (max. TA = 25°C) at VCC = 3.0 V RON = 1.8 Ω (max. TA = 25°C) at VCC = 2.3 V
  • Ultra low power dissipation: Icc = 0.2 μA (max.) at TA = 85°C
  • 4.3 V tolerant and 1.8 V compatible threshold on digital control input at VCC = 2.3 to 4.3 V
  • Wide operating voltage range: VCC (opr) = 1.65 V to 4.3 V single supply
